RULlNG-PEN.

SPECIFICATION forming part of Letters Patent No. 412,991, dated October 15, 1889.

Application filed February 21, 1889. Serial No. 300,643. (No model.)

To all whom it may concern:

Be it known that I, J ONAS S. SonERIN, of the city, county, and State of New York, have invented a certain new and useful Improvement in Ruling-Pens, of which the following is a specification.

I'will describe in detail a ruling-pen embodying my improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure 1 is an edge View of a ruling-pen embodying my improvement. Fig. 2 is a side view of the same. Fig. 3 is an edge view showing a ruling-pen embodying my improvement, but of modified form. Fig. 4 is a side view of the same. Fig. 5 is an edge view showing still another modification, and Fig. 6 is a side View thereof. Fig. 7 is a view of a ruling-pen embodyin g my improvement, showing a spreader and handle combined therewith.

Similar letters of reference designate corresponding parts in all the figures.

Referring first to Figs. 1 and 2, A represents a socket. This socket'is in the form of a split ring, the split being shown at a. Formed integral with the socket A are resilient jaws B. The jaws B are preferably formed integral with the socket A. Extending between the upper portions of the jaws B are wings or lips I). These wings are separated from each other by a longitudinally-extending slit 1), and they are separated from the socket A by a horizontally-extending slit 19 In this example the wings I) terminate at about midway in the lengths of the jaws B, and at or about bearing-points 0, formed upon the inner sides of the jaws. Preferably these bearing-points are formed by bending the jaws B inwardly, as may be readily seen from the drawings. Just above the bearing-points C are formed slits d, which are cut in from the front nearly to the wings I), and are shown clearly in Fig. 2.

The example of my improvement shown in Figs. 3 and4: is in all respects like that shown in Figs. 1 and 2, except that the wings I) are carried to the lower end or extremity of the pen. In Figs. 5 and 6 I have shown that the wings I) may be wholly omitted. In Fig. 7 the slits d are omitted.

To use this pen, a handle D, having a tapering end portion 6, constituting a spreader, is inserted through the socket A. By then pass ing the spreader portion 6 down between the bearing-points O the jaws may be opened to any desired extent. Normally the resilience of the jaws will cause them to remain closed, or substantially so. The wings I) tend to strengthen the jaws, while the slits tend to increase the resilience.

In all examples of my improvement the pen may be struck up from the single piece of metal and bent into proper shape.

A lead-pencil or any similarly-shaped article may be used to operate as the handle, and it will be seen that by myimprovement a very cheap and effective ruling-pen is made.

That I claim as my invention, and desire to secure by Letters Patent, is-

1. A ruling-pen comprising a socket c0nsisting of a split ring, resilient jaws extending from said socket, and bearing-points upon the inner sides of said jaws intermediate of said socket and the free ends of the jaws, substantially as specified.

2. A ruling-pen comprising a socket consisting of a split ring, resilient jaws extending from said socket, and bearing points upon the inner sides of the jaws intermediate of said socket and the free ends of the jaws, the whole being formed from a single piece of metal, substantially as specified.

3. The combination, with a ruling-pen comprising a socket consisting of a split ring and resilient jaws extending from said socket, pro vided with bearing-points upon their inner sides, of a handle comprising a tapering spreader portion adapted, when inserted through the socket, to contact with said bear.- ing-points to spread the jaws, substantially as specified.
